Allow for title before separator

[jbirnick]

This is a reminder for myself to possibly implement a way to enable a design like:

Theorem 5.2 (Fermat's last theorem). The equation ...

In other words, allow to have a separator after the title.

Please comment here if you need/want this. Please also comment what would be a good interface. The easiest way would be to introduce a separator value which is placed before the body, but I think it's not that clean...

I would find this useful. Modifying the separator would also be useful, so I can use a colon instead of a period, for example.

[jbirnick]

Well you can already replace the period by a colon in prefix, it's just about positioning.

You can use the colon with the following code in the definition of the mathbox: (source: https://forum.typst.app/t/great-theorems-how-do-i-include-something-before-content-but-after-the-title/1383)

bodyfmt: body =>[#h(-0.35em) : #body]

Even though this is not the cleanest solution, at least it works.

[jbirnick]

Still thinking how to implement/expose this... somehow I don't like the idea of a "separator", I think it's not that natural.

My plan was to offer an order field, which by default would be sth. like:

(prefix, titlix, body, suffix) => [#prefix #titlix #body #suffix]

Then for your usecase you could do:

(prefix, titlix, body, suffix) => [#prefix #titlix. #body #suffix]

(Notice the dot after titlix.) But now I realized that I guess this doesn't work because if there is no title, you would have space between the prefix and the dot. I don't see how to get around this with Typst functionality.

I was playing around with this and did some refactoring in my fork: https://github.com/shivangp76/typst-great-theorems

Using my fork, you can add the title before the separator with the following. Note that the only difference from the default is that the period is moved to the end.

  formatter: (blocktitle, number: none, title: none, body) =>  [
    *#blocktitle#if number != none [ #number]*#if title != none [ (#title)]*.*
    #body
    // NOTE: Custom suffix here
  ],

[jbirnick]

Hmm, i think the user shouldn't need to use any ifs in there code, but your example nevertheless gave some inspiration on how I might implement it.

[jbirnick]

Here is a temporary (or final?) solution which is better than using h(-0.35em). Namely, h(0pt,weak: true) kills leading whitespace, so just use:

bodyfmt: body => [#h(0pt,weak: true) *:* #body]
